Step 10—Electrical Connections
115-V WIRING
Refer to the unit rating plate or Table 6 for equipment electrical
requirements. The control system requires an earth ground for
proper operation.
Do not connect aluminum wire between disconnect switch
and furnace. Use only copper wire.
Make all electrical connections in accordance with the current
edition of the National Electrical Code (NEC) ANSI/NFPA
70-1999, and any local codes or ordinances that might apply. For
Canadian installations, all electrical connections must be made in
accordance with Canadian Electrical Code CSA C22.1, or authori-
ties having jurisdiction.
NOTE: Proper polarity must be maintained for 115-v wiring. If
polarity is incorrect, control status code indicator light will flash
rapidly and furnace will not operate.
